Re: [Groff] condition: OR of two string comparisons

Exactly.  Taking an earlier suggestion for OR, it's valid now.

    $ nroff | grep .
    .if 'a'a'b'c'
    b’c’
    $

However, a new syntax is needed.  I'd guess something at the start that
is currently invalid would indicate a whole new style of expression is
present, one with typical precedence, and more string matching
possibilities.

Cheers, Ralph.
